1 Claim. (Cl. 107-49) This invention relates generally to molds, such, prising a pair of non-yielding members formed for example, as confection molds or the like, and of suitable material, such as die cast aluminum, more particularly to a novel and improved reor the like, and between which is disposed in asmovable insert, whereby the same mold may be sembled position a solid piece of yielding mate- 5 adapted for the manufacture of a product of rial, such as soft rubber, or the like, all of said different sizes. parts being assembled by means of a screw ex- In the manufacture of such products as frozen tending therethrough, the head of the screw beconfections, or the like, the size of theproduct gening received in the upper of said non-yielding erally depends upon the nature of the confection. members and the lower threaded portion of said m Thus when the confection is in the form of a screw being received in threaded relation with l0 frozen sucker, which consists of a mixture of the lower of said members, whereby actuation of water and syrup, the same is of a relatively large said screw in the proper direction will effect a size, whereas when the confection is in the form compressing action on the intermediate body of of an ice cream block or a block of frozen custard rubber causing the same to expand to grip the the same is considerably smaller as the cost of inner perimeter of the mold, which gripping acif the ingredients which go into the manufacture of tion will securely lock the insert within the these products is considerably different. Heremold. tofore, therefore, in the manufacture of these A still further object of this invention is to provarious types of confections it was necessary for vide a device of the character described compristhe manufacturer to have a number of molds of ing a pair of non-yielding members between different sizes for the manufacture of these vawhich is disposed a solid body of yielding materious types of frozen confections. This, of course, rial, all of said members being assembled by involved an outlay of a considerable amount of means of a centrally disposed screwextending money for the various sizes of molds as well as through said members, said screw having the involving the taking up of space, etc., for the lower threaded portion thereof engaged within 2. storing and housing of these different molds. a threaded socket provided in one of said mem- It is, therefore, the main object of this inhers, whereby the actuation of said screw will vention to provide a novel and improved sanitary cause said non-yielding members to move towards insert which may be readily inserted and reor away from each other, said non-yielding memmoved from a confection mold to adapt the same bers being adapted for a snug fit within the mold, 3

In designing an insert of this character actuation of the screw will compress the yieldit is necessary to make the same so that it may ing member to cause the same to expand and to be readily disposed within the mold to reduce the thereby grip the inner perimeter of the mold to 5 size thereof, and when in such position, it should securely lock the insert in operative position. 85 prevent leakage of the ingredients to the bot- A still further object of this invention is to tom of the mold, should also be highly sanitary, provide a device of the character described, which and should at the same time be durable and will be simple in construction, assembly and 0peasily removed from the mold when it is desired eration, which will be sanitary and durable, -10 to replace the same or to entirely remove the which may be produced along lines convenient same. for low cost manufacture, and which will be It is another object of this invention to produce highly efficient for carrying out the purposes for an insert of the character described having all of which it is designed. the above advantages and one that may be readi- With the foregoing and other objects in View, 1y inserted into and removed from the mold with which will appear as the description proceeds, "a minimum of labor and time and without the the invention consists in certain novel features need of any equipment other than an ordinary of construction, arrangement and combination screw driver, and which when once disposed in of parts hereinafter more fully described, illusposition will be highly sanitary and will also protrated in the accompanying drawing, and parduce a confection of reduced size, the general ticularly pointed out in the appended claim, it 50 vide a device of the character described com invention.

Referring to the drawing in which the same characters of. reference are employed to indicate corresponding or similar parts throughout the several figures of the drawing:

Figure 1 is a View in perspective of a portion of a multiple confection mold showing a plurality of my improved inserts disposed in place inv the individual confection molds;

Fig. 2 is a sectional view through the bottom portion of an individual mold showing my improved insert in operative position in place therein;

Fig. 3-is a top plan view taken on line 3-3 of Fig.2;

Fig. 4 is a view in perspective of my improved insert, the same being shown in dotted lines'in expanded position; and

Fig. 5 is a view in perspective of the confection produced with said molds, the dotted lines thereon illustrating the different sizes of confections that maybe produced with said mold when employingjmy improved insert.

Referring to the drawing more specifically by charactersof reference, the numeral 1 designates a confection mold'within which are provided a plurality/of individual molds 2, which molds are employed for making frozen confections of the type illustrated in Fig. 5. As already explained, when it is desired to make a confection consisting of the ingredients of water and syrup, the unobstructed mold is employed producing a confection of comparatively'large size as shown at A in Fig. 5.

However, when the confection is to be made of ice cream or in the form of frozencustard, the same is to be of a smaller size, such, for example, as the size illustrated at B. or C in Fig. 5, and to produce that size it is necessary to insert in the individual mold 2 my improved insert [0, whereby the said mold may be reduced for producing a confection of. the desired size. As the specific construction of mold per se forms no part of the present invention, it is not thought necessary to describe the same in more detail.

My improved insert, which is generally designated by the reference character In, comprises in the embodiment illustrated a lower member I I, which is shaped as shown in the drawing and is adapted to. snugly-fit the lower portion of the mold 2. This member ll may be formed of any suitable material, such, for example, as die. cast aluminum, or the like, and is provided with a centralv passage or threaded bore I2 and has formed on its upper face a central projection 3 for the purpose to be presently more fully described.

(Jo-operating with said lower member II is a second member I which is also formed of suitable material, such as die cast aluminum, or the like, and which is shaped so as to snugly fit the interior of the mold at the point where the same contacts the mold when the insert is in operative position. The member I4 is provided on its lower face with a depending central projection I5 and acentral passage i6, which passage is of reduced diameter adjacent the lower portion thereof.

The upper face of the member I4 is hollowed out, as shown at If, to give to the confection formed within the obstructed mold the desired bottom configuration as shown by dotted lines at l8 in Fig. 5.

Mounted between the members H and I4 is a solid piece of yielding material I9, such, for example, as soft rubber, or the like, said member I9 being provided on its upper and lower faces with the depressions 20 and 2|, respectively, for receiving therein the projections I 3 and I5, respectively. The members H, I 4 and. I9 are assembled in operative position by means of the screw 22 extending therethrough, said screw being provided with the head 23 which is of enlarged diameter and which is received in the central opening 16 provided in the member Id. The lower portion of the screw is threaded, as shown at 24, and is adapted for being received in threaded engagement within the threaded opening I2 of the member H. A suitable recess-25 is provided in the upper face of the head 23 of the screw for receiving a screw driver, or the like, 26 by means of which the said screw 2-2 may be actuated. The head of the screw 23 is received in the opening [6, so that the upper surface thereof' will be flush with the upper surface I! of the member l4.

From the above it will be apparent that the actuation of the screw 22 will cause the members II and M to move either towards each other or away from each other depending upon the direction of rotation of the screw. Thus the screw 22 may be actuated to move the members II and I4 away from each other and to thereby release any pressure on the intermediate body of rubber 19.

When in. this position it will be apparent that the insert may be readily dropped into or removed: from the moldv 2 as it does not press on the inner'perimeter of the mold. However, when the screw 22 is actuated to move the members I I and I4 towards each other the body I!) of rubber will be compressed between said members and will cause the same to expand at the sides to the position indicated at 2'! by dottedlines in Fig. 4, in which position it. will be readily apparent that said body of rubberwill grip the inner perimeter of the mold and to thereby become securely locked in place therein. When in this position, the insert will fit sufliciently snug within the lower portion of the mold to prevent the leakage of any of the, liquid past the same.

It will also be apparent that by employing these inserts it will be necessary for the manufacturer to have only one size of mold with which he will be able to produce confections of different sizes. These molds are generally used at. the present time in the manufacture of frozen confectionson sticks, the confection, 30 having the. stick 31 embedded therein being an illustration of the type of confection produced with the use of these molds. As already explained, the smaller one, indicated by the letter C, may be an ice. cream block or a confection of frozen custard, whereas the larger one, indicated by the letter A,v may be a frozen sucker made up of water and syrup. It will also be understood that I dov not limit myself to the particular shape of mold and insert shown, as the principle involved may be readily employed with satisfactory results on any shape or type of mold.

It is believed that my invention, its mode of construction and assembly and operation, and many of its advantages should be readilyunderstood from the foregoing without further description, and should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are, nevertheless, capable of wide variation within the purview of my invention as defined in the appended claim.

What I claim and desire to secure by Letters Patent of the United States is:

In combination with a mold, of an insert adapted for disposition within the same for reducing the size thereof, said insert being adapted for completely filling the lower portion of said mold and being eifective when in operative position for preventing leakage past said insert to the lower portion of the mold, the upper portion of the mold when the insert is in place being .unobstructed thereby producing a molded article of substantially the same configuration but of a smaller size than the one produced in the original mold.
